		Case1 - Test just the Move
		1.Click Move 3 to X, the node 3 should move to node X and with correct Open State()
		2.if the bug is not fixed, you will see Node 3 doesn't have correct state (currently, it was closed but has opened icon)
		3.Click Move 3 to 2, should has same result.
		Case2 - Test move and with modify
		1.Click Move 3 to X, the node 3 should move to node X, and both node2 and nodeX has correct label change (Node (1) ..etc)
		2.Click Move 3 to 2, the node 3 should move to node 2, and both node2 and nodeX has correct label change (Node (1) ..etc)
		3.if the bug is not fixed, you will see Node 3 disappear
